Constructor Detail

LinearDelayRetryPolicy

public LinearDelayRetryPolicy(int maxRetries,
                              int delayMs,
                              boolean noDelayOnFirstRetry,
                              double jitter)

Creates a new LinearDelayRetryPolicy with the specified maximum number of retries, and a constant delay for retry attempts.

Parameters:

maxRetries - A positive value representing the number of retry attempts allowed by the LinearDelayRetryPolicy.

delayMs - A positive value representing the constant delay between retry attempts, in milliseconds.

noDelayOnFirstRetry - true for the first retry to be attempted immediately, otherwise false for the first retry to be attempted after delayMs.

jitter - The factor multiplier to be applied to delayMs to thereafter be added to the delay for each retry.

Throws:

IllegalArgumentException - If delayMs, maxRetries or jitter is negative.

Method Detail

getDelayMs

public long getDelayMs(int attemptNo)

Description copied from class: RetryPolicy

Returns the delay in milliseconds for the specified attempt number. This method is intended to be implemented by a subclass to define the backoff function for retry attempts.

Specified by:

getDelayMs in class RetryPolicy

Parameters:

attemptNo - The attempt number, starting with 1.

Returns:

The delay in milliseconds for the specified attempt number.
